WH EEL-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 487,882, dated December 13, 1892. Application filed September 12, 1891. Serial No. 405,468. (No model.)

To all whom it may concern.-

Be it known that I, ELIJAH A. OvENsHIRE, a citizen of the United States, residing at Lansing, county of Ingham, State of Michi- 5 gan, have invented a certain new and useful Improvementin Wheeled Cultivators; and I I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which ro it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specitication.

This invention. relates to wheeled cultivators, and has for its object the arrangement r 5 of the details going to make up a cultivator, by means of which the various operative parts may be so adjusted as to do most efficient work and be at all times under the immediate control of the operator.

In the drawings, Figure 1 shows in perspective the parts assembled in their proper position. Fig. 2 is a detail of the adjustable handle attachment; Fig. 3, a detail of the framework; Figs. 4, 5, and 6, details of the 2 5 adjustable shovel-holder and break-pin. Fig. 8 is a detail of parallel bars controlling the lateral movement of the rear shovels of the cultivator. Fig. 7 is a detail of the adjusting part of the forward end of one of the parallel rods of Fig. 8. Figs. 9 and 10 are details of a separating-fork used to hold the shovel-bars at a fixed distance apart. Fig. 11 is a detail of the hinge by which the shovelbar shown in Fig. 8 is attached to the sliding 3 5 support on the hanger H, which supports the forward end of the shovel-bars.

A represents the vpole to which are bolted the metal pieces o and b, forming a braced support or holding-frame to which are attached the ends of the axle-arms B. The axle-arms B extend downward and are turned outward and terminated by the axles proper b', upon which are received the supportingwheels b2. Forward of the axle, depending 45 from the framework a, is a hanger H, secured` to the framework by means of the clips or` links h. The lower ends of the hanger H. are bent at right angles with the depending armh' and furnish horizontal supports, upon each 5o one of which is adj ustably fixed a hinge-piece I. The hinge-piece I is movable horizontally along the horizontal part h2 of the hanger H, and held in place by a set-collar I', inserted through an aperture in the hinge-piece I around h2, and secured to h2 by a set-screw I2. 55 On one end of the hinge-piece I is a Vertical hinge formed of the partsrl and o", (shown in Fig. IL) held together by a bolt and nut. t" is made in two halves, each of which has a concave branch or arm adaptedto rest upon and o o be bolted to the shovel-arm J, which is preferably a piece of -round hollow pipe. The other end of the hinge-piece I has a iiat corrugated table with an oval perforation.. through it. Upon the upper side of the cor- 65 rugated table rests the flatcorrugated bottom of a pivot I3, which is inserted through an eye in the parallel rod K.

To the rear of the shovel-bar J is hinged an extension J', carrying the two shovels S S, 7o one being on the outside and the other on the inside of the extension J On the inside of the extension J is also an arm or projectionlo', receiving the hooked end of the parallel rod K. Each shovel-blade'is held to the exten- 75 sion J by a holder. (Shown-in detail in Figs.

4, 5, and 6.) This holder consists of a circular plate P, having a lobe p below it perforated with a slot curved concentric with the center of the plate P. The plate Pand the lobep and 8o extension J are preferably-made in one piece. Upon the circular part of the plate P rests the flat end of a cup P', also having a lobe furnished with a hook p. The outer or hollow end of the cup P' has a circular seat to receive 85 the round standard S of the shovel-blade, and the standard of the shovel-blade is held in the seat of the cup P by anfeyebolt f2, of which the eye passes around the standard S of the shovel-blade, throughga perforation in the bot- 9o tom ofthe cup P', through the perforation in the plate P of the extension J', and all the parts are secured together by the bolt andnut j. A bolt and nut d, passing through the curved slot in the lobe p and through the 95 open slot of the hook p', holds the cup and plate securely in position between the extreme limits of the-slot in the lobe p The hook inthe lobe p' is directed forward and tension enough is given to the bolt and nut CZ roo to hold the shovel-blade at the desired angle Should, however, the

under ordinary use.

shovel-blade strike` any unusual resistances, J

like a stone or root, the shovel-blade-would be forced backward,the hook p' forced out from under the head of the bolticl, and the shovelblade allowed to slip over the obstruction without breaking any of the. holding parts.,

By means of the parallel bar K, adjustable at 7c, the extension J may be swung either way with respect to the main bar J, and the track of the two shovel-blades S S may` be; widened or narrowed at will.

About midway from the front to the rear of the main bar J is a ring QShowrr in Fig. 8 and in Fig. 10.) This ring is clamped to the body ot' the bar J, and on its upper side furnished with a number of perforations or eyes, toene of which o" is attach-edi a link r2; reaching upward and tor-'ward to.- a lifting? handle R attached to the frame a and serv'- ing to litt the rear end ot the shovel-bar Ji. Into anotherof these eyes r is placed the foot oi7 a spreader-legl Fig. lOI represents a spreader, ot which the two leg-sl L L are adj usta'blfy held together by bolt and nut' mf, passing through and holding together thel corrugated plates fm? and m3. The spreader mayI beset at any angie between zero and one hund-red and eighty-degrees, and serves to hold the lawo shovel-bars J' at a tiered; distance apart, which distance is adjustable,

according to the work` to be performed. The` spreader is held upright by a. chain or link passing from the eye mf'- to the cross-bar of the argl-e.v

@represents a seat-iron for the handle 0. This seat-iron presentsl a fiat corrugated' upperl surface and receives a dat corrugated lower-surface of ka toot-iron of', the two parts bein-gj held together by*v the bolt, which' secures both of; them to the shovel-bar J at the poi-nt o2. portion is furnished with a slotted pertora tion concentric with the bolt o3, the second perforation o4 receiving a second bolt ofi-that holds the wooden part yof the handle 0; to it. The wooden handle 0- exten-ds upward and backward in the for-rn of anordin-aryfeultira-V tor or plow handle. Just forward of thehandle seat-iron o is placed a foot-rest The parts when assembled together make a compl-ete wheeled or sulky culti-vater, iin which lthe shovel-ba-rs may be adjusted to any widthand tovari'ous angles with respect to each other, and adjusted to track either one behind the other, sor as. to work in the same furrow,v or to track in dii'erent furrows across thek entire pathbetween the wheels ot' theonltivator` A seatV, attached to the framework, per mits the use ot a wheeled harrowv as; a Su-lkybarrow, if desired.

The liftingghandle R", operating through the link or eye r and ring R', lifts the rearI end of the shovel-arm J and extension l', turning it around the horizontal extension I' of the hanger H.

FFhe toot-iron o" at its; upper or rear T T represent ratchet-quadrants securely fastened to theframe-pieces. a a.. At'the center of each quadrant-rack T is the turningpin of the handle R', and the handle R is securely held by the teeth of ythe quadrant- ,j rack in, whatever positionit may be placed. .y Contact between the handle R" and the rackteeth i's maintained by a leaf-spring t, bolted to the rack and linked to the forward end of the-handle R. The surface of the quadrant-` rack, to which the spring t is bolted, is inclined slightly across the axis of the pin r4, and @S the linked. end of the spring is drawn downward it is also thrown outward 'and' forces the hand'le close up against the Arack-teeth. The contact is released by pushl ing the handle outward against thetension or ithe spring. i

An eve-ner V crosses the pol'eand holds at either end a suspended arme, from the bot.- Ftomx ot which a draft-rod fr! extendsto thehanger H or hingecasting L. Thew-hifdetree; is` hooked tothe suspended arm fu at any elevation, and thus. the forward draft maybe arranged to balancev the weight;l of the rider, because by raising the point of drait on the han-ger H the pull comes more alo-ng the 11i-ne of the. pole, and the forward end of that pole Lis depressed and the seat,I withA its occupant, iraised, by lowering the whifdetree the reverseaction takes piace. By aproper ad- 1" jlustm-ent the downward thrust, due to the Iweigh-t of the rider, is perfectly' balanced?.
